| Summary: | The trend of Eastern Bering Sea pollock biomass increasing were stable by the end of 1990-s and early 2000-s as result of annual recruitment by average 1995, 1997-1999 and numerous 1996, 2000 year classes. Pollock biomass had increased for 61% in period 1996-2002. The oceanology condition and pollock spatial distribution were close to average at first part of 1990-s. Some signs of cooling had appears in the Bering Sea by the end of 1997 and it have maximum in 1999. At the same time, cold period in the Bering Sea was short and new warming process began in 2001-2002. The high positive water temperature anomaly observed in the Bering Sea in 2003-2004. There is direct interrelationship between distribution of pollock and variability of oceanology condition, basically of water temperature, in summer-autumn time. Distribution of pollock in the northwestern Bering Sea have big scale interannual variability depends of changing water temperature. Scale of pollock distribution into northwestern Bering Sea much higher in period warm oceanology condition. Indicated interrelationships between interannual variability of the Eastern Bering |
